Feasibility and safety of intraoperative bile duct clearance by antegrade transcystic balloon sphincteroplasty: A prospective observational pilot study.

Background: Concomitant cholecystolithiasis and choledocholithiasis are common. Standard treatments are endoscopic retrograde cholangiography (ERC) followed by cholecystectomy or laparoendoscopic rendezvous. Endoscopic retrograde cholangiography has drawbacks, such as post-ERC pancreatitis or bleeding, and potentially more than one intervention is required to address common bile duct (CBD) stones.

Impact of Fetal Weight Estimation on the Prediction of Neonatal Morbidity and Mortality at the Limit of Viability.

Introduction: To determine the accuracy of estimated fetal weight (EFW) at the limit of viability in a delivery room setting and its impact on the prediction of neonatal outcome.

Material And Methods: In this retrospective, single-center cohort study we included patients with preterm birth between 230/7 and 260/7 weeks of gestation. Neonates were divided into 3 groups according to birth weight at delivery (accuracy index 90-110%, <90%, >110%).

Factors influencing the accuracy of fetal weight estimation with a focus on preterm birth at the limit of viability: a systematic literature review.

Background: Fetal weight estimation (FWE) is an important factor for clinical management decisions, especially in imminent preterm birth at the limit of viability between 23(0/7) and 26(0/7) weeks of gestation. It is crucial to detect and eliminate factors that have a negative impact on the accuracy of FWE.

Data Sources: In this systematic literature review, we investigated 14 factors that may influence the accuracy of FWE, in particular in preterm neonates born at the limit of viability.

Genomic structure and functional characterisation of the promoters of human and mouse nogo/rtn4.

The reticulon-family member Nogo-A is a potent neurite growth inhibitory protein in vitro and may play a role in the restriction of axonal regeneration after injury and of structural plasticity in the CNS of higher vertebrates. Of the three major isoforms of Nogo, Nogo-A is mostly expressed in the brain, Nogo-B is found in a ubiquitous pattern, and Nogo-C is most highly expressed in muscle. Seven additional splice-variants derived both from differential splicing and differential promoter usage have been identified.
